Greater efficiency and reliability

In the demanding environment of defence, where every detail has a direct impact on the safety, performance and operability of vehicles, the correct tensioning of the tracks is a critical factor. Piedrafita, a leading company in technological innovation for military mobility, presents its hydropneumatic track tensioner, an advanced, robust and fully personalised solution designed to maintain optimum track tension at all times.

The track  tensioner is an essential part of track vehicles, especially in rough terrain or under extreme conditions. Its role goes far beyond keeping the track taut: it directly influences vehicle handling, crew comfort, fuel consumption and the life of both the track and the suspension system.

Technology that makes the difference

The hydropneumatic system developed by Piedrafita offers a unique combination of high compression and extension performance, allowing it to automatically adapt to changes in tension caused by terrain or track wear. Thanks to its adjustable gas preload, the tensioner can be configured specifically for each type of vehicle, mission or operating environment.

One of its key features is its ability to operate in extreme climatic conditions, from -46°C to 120°C, making it a reliable component for operations in high mountain, desert or arctic climates. In addition, its compact and lightweight design (750 x 155 x 250 mm and 30 kg in weight) makes it ideal for both new developments and retrofitting existing armoured platforms.

Automation and precision from inside the vehicle

The Piedrafita Systems track tensioner allows the tension to be adjusted automatically without the need for external intervention, optimising the vehicle's operating time. This adjustment can be carried out from inside the vehicle, providing added safety and efficiency for the crew.

The ability to integrate it with advanced diagnostic systems (HUMS) makes this tensioner a key part of predictive maintenance programmes. In addition, it is compatible with both steel link and continuous rubber chains, where it even incorporates a collapsible function to adapt to their particularities.

Designed for vehicles up to 70 tons

The Piedrafita track tensioner has been designed to operate on vehicles up to 70 tonnes, covering a wide spectrum of military platforms. Its reliability, modularity and configurability make it the ideal choice for fleet modernisation programmes and for new armoured developments that demand maximum mobility and durability.
